Oliver 1650

Last Updated: July 2024

Overview

The Oliver 1650 is a versatile row-crop tractor produced by Oliver between 1964 and 1969. It was available in both two-wheel drive (2WD) and optional four-wheel drive (4WD) configurations. Equipped with a Waukesha-Oliver engine and multiple transmission options, it delivered up to 66.48 horsepower at a rated RPM of 2200. It supported various tire arrangements and was capable of handling a range of agricultural tasks with differential disc brakes. The Oliver 1650 offered the farmer an open station or an optional cab for more comfortable operation. According to independent test results, the tractor exhibited a maximum torque of 256 lb.-ft. (347 Nm) at 1320 rpm, a torque rise of 18%, and a maximum force exerted of 5840 lbs (26.0 kN) at the hitch points. The hydraulic system had a pump delivery rate of 12.4 GPM (46.9 l/min) and a hydraulic power of 18.5 HP (13.8 kW) at 2100 psi (145 bar). The fuel efficiency at the standard PTO speed of 540 rpm was 13.60 Hp.hr/gal (2.68 kW.h/l), with a fuel consumption of 4.24 Gal/hr (16.05 l/h) at 1650 rpm. The tractor remains a capable machine for a variety of farming applications.
